Pull x86 fixes from Borislav Petkov: "The three SEV commits are not really urgent material. But we figured since getting them in now will avoid a huge amount of conflicts between future SEV changes touching tip, the kvm and probably other trees, sending them to you now would be best. The idea is that the tip, kvm etc branches for 5.14 will all base ontop of -rc2 and thus everything will be peachy. What is more, those changes are purely mechanical and defines movement so they should be fine to go now (famous last words). Summary: - Enable -Wundef for the compressed kernel build stage - Reorganize SEV code to streamline and simplify future development" * tag 'x86_urgent_for_v5.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/compressed: Enable -Wundef x86/msr: Rename MSR_K8_SYSCFG to MSR_AMD64_SYSCFG x86/sev: Move GHCB MSR protocol and NAE definitions in a common header x86/sev-es: Rename sev-es.{ch} to sev.{ch}

Merged at -rc1 to avoid some conflicts during the merge window. - Initialise RGSR_EL1.SEED in __cpu_setup() as it may be left as 0 out of reset and the IRG instruction would not function as expected if only the architected pseudorandom number generator is implemented. - Fix potential race condition in __sync_icache_dcache() where the PG_dcache_clean page flag is set before the actual cache maintenance. - Fix header include in BTI kselftests" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Fix race condition on PG_dcache_clean in __sync_icache_dcache() arm64: tools: Add __ASM_CPUCAPS_H to the endif in cpucaps.h arm64: mte: initialize RGSR_EL1.SEED in __cpu_setup kselftest/arm64: Add missing stddef.h include to BTI tests arm64: Generate cpucaps.h

ACPI: NFIT: Fix support for variable 'SPA' structure size

2021-05-12T19:38:25Z

ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical Address (SPA) Range Structure". The presence of that new field is indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4 firmware implementations omit the flag and maintain the original size of the structure. Update the implementation to check that flag to determine the size rather than the ACPI 6.4 compliant definition of 'struct acpi_nfit_system_address' from the Linux ACPICA definitions. Update the test infrastructure for the new expectations as well, i.e. continue to emulate the ACPI 6.3 definition of that structure. Without this fix the kernel fails to validate 'SPA' structures and this leads to a crash in nfit_get_smbios_id() since that routine assumes that SPAs are valid if it finds valid SMBIOS tables.

tools/testing/nvdimm: Make symbol '__nfit_test_ioremap' static

2021-05-12T19:37:14Z

The sparse tool complains as follows: tools/testing/nvdimm/test/iomap.c:65:14: warning: symbol '__nfit_test_ioremap' was not declared. Should it be static? This symbol is not used outside of iomap.c, so this commit marks it static.

objtool/x86: Fix elf_add_alternative() endianness

2021-05-12T19:17:01Z

Currently x86 kernel cross-compiled on big endian system fails at boot with: kernel BUG at arch/x86/kernel/alternative.c:258! Corresponding bug condition look like the following: BUG_ON(feature >= (NCAPINTS + NBUGINTS) * 32); Fix that by converting alternative feature/cpuid to target endianness.
